Abstract

We analyze the local accuracy of the virtual element method. More precisely, we prove an error bound similar to the one holding for the finite element method, namely, that the local \(H^1\) error in a interior subdomain is bounded by a term behaving like the best approximation allowed by the local smoothness of the solution in a larger interior subdomain plus the global error measured in a negative norm.

虚拟元素法的内部估计

我们分析了虚拟元素方法的局部精度。更准确地说，我们证明了一个与有限元法类似的误差约束，即内部子域的局部误差由一个项约束，这个项的行为类似于较大内部子域中局部平滑解所允许的最佳近似值加上以负规范测量的全局误差。

期刊介绍： Numerische Mathematik publishes papers of the very highest quality presenting significantly new and important developments in all areas of Numerical Analysis. "Numerical Analysis" is here understood in its most general sense, as that part of Mathematics that covers: 1. The conception and mathematical analysis of efficient numerical schemes actually used on computers (the "core" of Numerical Analysis) 2. Optimization and Control Theory 3. Mathematical Modeling 4. The mathematical aspects of Scientific Computing
